Abstract: Under the background of global energy transformation and the pursuit of low-carbon development in mining industry,this paper explores the development trend of battery-electric mining trucks and provides strategies for their green and sustainable development in mining industry. By combing the global and regional market status of battery-electric mining truck, the market differences and policy drivers in different regions are analyzed. Explore core technologies such as batteries,charging,and autonomous driving,analyze the progress and limitations of existing technologies and the development potential of new technologies,and discuss the challenges and development trends of charging infrastructure. By listing the application examples of Zijinshan copper-gold mine,Boliden mine and other open-pit and underground mines,the technical characteristics and operational benefits are summarized. The results show that compared with the traditional diesel mining truck,the battery-electric mining truck can reduce the operating cost by 50% to 60%,reduce carbon emissions by more than 25%,and effectively improve the operating environment,which is the key technical path for the green transformation of mining industry. For mining enterprises,they should give priority to the deployment of battery-electric mining truck in scenarios with short-distance heavy load and high round-trip frequency,and actively explore innovative operation modes such as ′vehicle-electricity separation′. Although there are challenges in battery life,charging facilities and initial investment,these problems will be gradually solved with technological progress,industrial ecology improvement and policy support. In the future,battery-electric mining truck is expected to be widely used in the world,promote the transformation and upgrading of mining industry to intelligent,unmanned and green, and contribute to the sustainable development of global mining industry. 

Key words: battery-electric mining truck,charging and battery-swapping technology,carbon neutrality,green mining
